Has anyone issues keeping the slip chuck on the valve stem. Paid $100 for this German engineered pain in the back side. I get to 110 psi and it pops off the stem. Are there any clamp style alternatives?

Bite the bullet / ignore the cost and get yourself a Hirame Pump Head. This is the best quality piece of bike related kit I have ever owned - beautifully designed, beautifully engineered and is a simply joy to use every time.

I've had the opposite problem with threaded stems when I use the pump at the lbs. It really grabs and it feels like I am pulling a file through a hole in some rubber, cant be good for the pump chuck. (So I use his old screw on now)

Just wondering if your chucks seal could be worn because of previous use on threaded valve stems?

ummmm....with all due respect because one has to thread it on which makes the whole operation a PIA thus poorly engineered............ in my opinion.

The Hirame pump head has a tapered twin diameter shank / sleeve which will fit inside most rubberised pressure hoses found on floor pumps. The head is simply held onto the hose with a small hose clamp. It's sold a a stand alone head with replacement valve seals avail.

No, it actually works very well. It does thread on (small time penalty), but this gives a more secure seal. And see that black button on it? ABS stands for 'air bleed system' - when inflated push the button and the hose pressure is released. You can now un-screw the chuck with no air loss from the tyre.

Read and comprehend the OP. he is looking for a" clamp style alternative" - I read nothing about threaded style chucks in the OP. .................
